CEO of the MPAA Dan Glickman says he’ll step down when his contract expires in September 2010, according to Politico. Glickman has held the post since September 2004, while his predecessor Jack Valenti headed the trade organization for 40 years. “The combination of a high salary and high-profile mingling with celebrities makes it one of Washington’s most coveted jobs,” says Politico, but it “poses serious challenges, including dealing with the competing agendas of the six movie studios.”
